Om has turned to ugh at the celebrity-studded Upper East Side apartment tower that was touted as the city’s first “spa-dominium.”

The ultra-luxury Miraval Living spa, boasting a heavily hyped “wellness center” and elaborate yoga facilities, has pulled — or been booted — out of 515 E. 72nd St. before the long-delayed massage and meditation palace even opens.

The 39-story high-rise — the setting for Bravo’s reality show “Double Exposure” — began converting its 365 rental apartments to condos a few years ago.

The spa — spawn of Arizona’s famed fitness resort — was supposed to help draw buyers willing to spend millions for an uptown aerie. The building owners changed its name from River Terrace to Miraval Living.

But sales have been sluggish. And four years after the spa was announced as the building’s chief amenity, it still isn’t finished.

This week, stunned residents received letters under their doors from Miraval saying, “We too have had a difficult time” with the building’s owner and developer.

“Due to their continual default on a contractual agreement, we can no longer manage the spa” and related amenities.

But hours later, the residents got a note from the building’s manager stating that the owners were fed up with Miraval, saying its “refusal to agree on a spa opening date . . . ultimately was a breaking point.”

The letter said the owners want to find a “local operator who is familiar with the New York City market” to replace Miraval and finally get the pleasure palace open.

One resident fumed, “The spa was a big reason why we moved here, and now we’re screwed.”
